IMPACT — A common building block to enable next generation radar arrays
Abstract
This paper discusses the progress of this team's project known as IMPACT (Integrated Multi-use Phased Array Common Tile), which addresses a major goal of the DARPA Arrays at Commercial Timescales (ACT) program. The goal of this program has been to develop a common technology base for Electronically Scanned Array (ESA) systems. Historically, most fielded ESA systems have been comprised of highly tailored, application-specific layers. This has led to slow design cycles, costly components, and significant portions of the total cost of ownership being invested in the up-front Non-Recurring Expenses (NRE). The results section highlights the receiver side of our progress.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
